Director James Cameron shows off a pair of 3D glasses before a promotional event for "Avatar", January 28, 2010.Christian Hartmann/Reuters"Titanic" director James Cameron, famous for creating innovative 3D filming techniques used in his colossal hit "Avatar," will try to revolutionize 3D technology once again with continued research into ways to make it glasses-free in theaters.

It's not clear yet whether or not Cameron will be able to achieve his goal of creating glasses-free 3D technology for theater projectors, but it's still a possibility ahead of the upcoming "Avatar" sequels.

Cameron has talked about glasses-free theater projection in the past. Last fall, while accepting an honorary membership from the Society of Motion Picture and Television Engineers, Cameron made the following statement:

"I'm going to push. Not only for better tools, workflow, high dynamic range and high frame rates — the things we are working toward. I'm still very bullish on 3D, but we need brighter projection, and ultimately I think it can happen — with no glasses. We'll get there."

Cameron's production company, Lightstorm Entertainment, recently renewed its 5-year contract with the light projection company Christie Digital Systems, according to The Hollywood reporter. Christie is known for supplying Lightstorm with RGB light projectors, considered to deliver top-of-the-line brightness and image quality, ideal for projecting 3D films.

The renewal of Lightstorm's deal with Christie, as stated by the press release on Christie's website, is contingent upon the two companies sharing their collective 3D knowledge and developing new 3D technology together, one of those new technologies potentially being glasses-free projectors. Christie will also provide Lightstorm with its brand new RGB laser projection series that's currently in the works, speculated to be key in creating this new glasses-free 3D tech. It's unclear yet how exactly this new 3D technology will be made possible.

For now, the only thing that's certain is that four — yes, four — "Avatar" sequels are on their way.
